Interface Chemistry

Material classes and mechanical tolerances

Zero Phase Degradation

KryoSheet graphene thermal pads

Solid-state carbon structure eliminates pump-out and dry-out across bare-die graphics processors and server CPUs. Anisotropic thermal conductivity provides industrial heat dissipation without curing schedules or liquid migration.

Peak Liquid Metal Transfer

Conductonaut gallium alloy

High-efficiency eutectic alloy formulated strictly for nickel-plated copper coldplates and direct silicon heat spreaders. Demands non-conductive barrier coatings over exposed SMD capacitors and complete exclusion from aluminium radiators.

Variable Gap Bridging

PhaseSheet and Minus Pad series

Formulated for uneven height differentials across video memory banks and voltage regulator modules. Viscoelastic compliance fills component gaps without excessive mechanical PCB deflection or oil leaching into board traces.

Substrate Compatibility

Electrical conductivity and coldplate criteria

KryoSheet dry installation protocol

Conductonaut electrical isolation criteria

Graphene microstructures require zero paste layering or liquid primers. Pre-cut dimensional sheets must sit flush against silicon without perimeter folding to prevent air pocket insulation under standard spring-tension brackets.

Gallium alloys are electrically conductive and will rapidly amalgamate with aluminium heatsinks. Technicians must verify nickel-plated contact surfaces, apply conforming protective lacquer to perimeter resistors, and meter exact mechanical mounting pressure.

Aeronaut and Kryonaut paste tolerance

Silicone and metal oxide compounds formulated for non-conductive application on standard integrated heat spreaders. Designed for standard desktop assemblies where electrical isolation must remain entirely non-critical.
